What is Manuals Aid?

The Malwarebytes research team has determined that Manuals Aid is a browser NewTab. These so-called "NewTabs" can manipulate your browser(s), for example to change your startpage or searchscopes, so that the affected browser visits their site or one of their choice.
This particular one is a newtab hijacker and uses web push notifications.

How did Manuals Aid get on my computer?

Browser hijackers use different methods for distributing themselves. This particular one was downloaded from the webstore:

after a redirect from their website:

How do I remove Manuals Aid?

Our program Malwarebytes can detect and remove this potentially unwanted program.
You can use their own uninstall instructions first, but I would advise to follow the steps below anyway.

  • Please download Malwarebytes for Windows to your desktop.
  • Double-click MBSetup.exe and follow the prompts to install the program.
  • When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
  • Click on the Get started button.
  • Click Scan to start a Threat Scan.
  • When the scan is finished click Quarantine to remove the found threats.
  • Reboot the system if prompted to complete the removal process.

Is there anything else I need to do to get rid of Manuals Aid?

  • No, Malwarebytes' Anti-Malware removes Manuals Aid completely.
  • If you have allowed the notifications you can read here how to disable them.

How would the full version of Malwarebytes help protect me?

We hope our application and this guide have helped you eradicate this hijacker.

As you can see below the full version of Malwarebytes would have protected you against the Manuals Aid hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
